Dear student
Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.
Fluorine is the most electronegative element. Fluorine has an electronegativity of 3.98 on the Pauling Electronegativity Scale and a valence of 1.

Fluorine is the most electronegative element because it contains 5 electrons in its 2p shell. The optimal electron configuration of the 2p orbital contains 6 electrons. So since fluorine is so close to inert gas configuration the electron are held lightly to the nucleus.
